Living your daily life in a shonen anime seems to be wrong.

As for what the other world is like...

That's not important.

"So, you've found a way back?"

"more or less."

What does "almost" mean?

"There's a key problem that hasn't been solved yet: I can't accurately pinpoint the coordinates of the world I was in before."

Qi Ye shook his head.

The only problem now is this. Although it's not impossible, the probability is so low that it's almost impossible to achieve.

Philip doesn't understand these things.

Chelsea didn't quite understand either; she had absolutely no concept of spatial coordinates or anything like that.

So I just shrugged.

"Why don't you just use our current world as the origin of that coordinate system?"

"What does this world do... huh?"

Qi Ye was about to shake his head, but then suddenly seemed to be deep in thought.

Using this world as the origin of the coordinate system is obviously not feasible. Even if you were to create spatial coordinates, you wouldn't know which world those coordinates correspond to.

But using another world as the origin of coordinates seems possible.

For example, the original world.

That is, the world where Shichiya was a native.

Apart from that world, all the worlds we've experienced so far can be considered mere fantasies within that world, what we call the two-dimensional world.

In other words, the worlds we live in now can be considered to exist based on the original world.

These worlds appeared at different times in the original world.

"Um……"

Qi Ye bit her nails as she continued to ponder.

Perhaps a timeline could be used as a coordinate axis, but time has neither a beginning nor an end...

Perhaps we could use the concept of "two-dimensional world" as the origin? Then, the year, month, and day could be used as the X, Y, and Z axes respectively, and the time when the work was created could be the corresponding coordinate point.

"Wait, wait, wait..."

Qiye continued biting her nails.

This seems feasible, although different works may appear on the same day, but this would greatly reduce the scope of the search.

However, there's still a problem...

Chelsea.

"what?"

"I'll need you to take care of Febri and Mine from now on. I need to go into seclusion for a while to do some serious research."

"Oh."

Chelsea nodded.

Although she didn't know what Qiye wanted to do, since Qiye had already said so, and she didn't have much to do anyway, she agreed.

Besides, taking care of Febri and the others isn't troublesome; the only one who needs looking after is Febri.

As for Mine, she's a girl who has commanded thousands of troops in battle; does she really need someone to take care of her?

Red eyes and black eyes are both unnecessary.

"Fibril, you'll be staying with Chelsea for a while. You need to be obedient, understand?"

Where is Qiye going?

"I need to carefully study how to get back. In short, we need to be fully prepared before we can return to Academy City, understand?"

Qi Ye laughed, ruffled the little girl's hair, and messed up her smooth golden hair.

Philip didn't pay any attention.

Hearing what Qiye said, she nodded obediently.

"Well, I see."

"Great, once I get out, maybe we'll be able to go back."

Qi Ye patted the little girl's head again.

He nodded again to Chelsea and was about to leave.

But Akame and Kurome walked in.

"What do you mean by 'go back'? Go back to where? Jinrui City?"

"No."

Qi Ye shook his head.

However, he didn't say much. Now that he knew there was a possible way to go back, he couldn't wait to study it carefully.

"In short, if you want to know, let Chelsea explain it to you. I'm leaving now."

Without waiting for Akame and Kurome to say anything, she ran directly into the space of her right eye.

Red Eyes and Black Eyes exchanged a glance.

The two sisters didn't understand what Qi Ye was up to, so they could only look to Chelsea, hoping she could answer their questions.

Chelsea was also somewhat helpless.

"Don't look at me, I'm not sure either."

She shook her head.

Although Qi Ye explained patiently, she didn't quite understand. Although the technological level of this world was relatively high, the basic education was not very good, and she had never even heard of theories about space.

"Anyway, according to Qiye, neither he nor Feibuli are from this world. They just came to this world by accident. Now they are researching ways to return to their original world."

That's all she could understand.

Chapter 336: Time to Go Home

Time travel is not an easy thing.

Seven Nights experienced three time travels. The first time was unconscious, purely due to his own abilities that he was transported to the ninja world. The second time was an accident; when the experimental space tore apart, he was sucked into the spatial rift he created.

The third time was similar, mainly because of Kaguya.

Now, Shichiya wants to travel through time for the fourth time, with the main goal of returning to Academy City and then to the ninja world.

It's hard.

Fortunately, we already have a plan, and it's a generally feasible one.

The world is too big, and that "transfer station" is too big; no matter where you take it as the origin, it's inaccurate.

Therefore, I plan to use time to determine the location.

Time, like space, can theoretically be controlled by anyone, because we live not only in space but also in time. Space and time are closely related to every person, every living being, and even every inanimate object.

"However, according to this theory, everything is interconnected, which means that theoretically, everyone should be able to master any kind of ability."

Qiye pondered this.

Just like the Jonin in the ninja world who train in other chakra natures, Shichiya is also trying to convert natural energy into other abilities.

Natural energy is a magical thing.

So far, it is everywhere, even in a different world. Even in the space developed by Qiye's right eye, there is natural energy. This thing may be one of the foundations of the world.

Since it is the foundation, it means that all sorts of things can be derived from natural energy.

It's mainly about ability.

Qiye had his clone research this aspect, while he mainly focused on spatial abilities.

There are also clones specifically responsible for researching mental abilities.

And how to access time...

Nanaya doesn't see this as a problem either; Esdeath is a perfect example.

Esdeath is not a time-manipulation user, or even a user at all; she simply mastered the power of ice through her Imperial Arms.

But this "ice" can affect time.

However, she can only use this ability, not master it.

Let's leave that aside for now.

According to Qiye's speculation, perhaps when a certain ability becomes powerful enough, it will affect the "rules".

For example, Esdeath's ice.

Ice gives people the impression of coldness and freezing, and freezing in general means freezing or encasing something.

Esdeath is different; what she freezes is not something else, but "time and space".

What about space?

If spatial abilities are powerful enough, wouldn't it be possible not only to travel to different worlds, but also to travel to different points in time?

It is theoretically feasible.

However, what Qiye needs to study now is not that, but how to travel to different worlds effectively.

Once a clear direction was established, all the research proceeded smoothly.
